Motor programming + spindle speeds and Reverse:

  • The motor speed can be programmed to operate in any range chosen by the user.
    Between 200 and 4,500 RPM's.
    Note: Settings are limited to 10 RPM intervals.
  • The full range of speed (RPM's) can also be controlled with just the speed control knob.
  • Speed control programming only requires a few easy steps.
  • Reverse is simple, just click the center button on the bottom part of the controler.
    See second video above showing controler operation.
  • Programming includes the ability to set bottom and top RPM range separately. In other words you can program the system to run the spindle at any speed or range of speeds you choose (see below).
    Slowest speed achievable: Motor 200 RPM. (Below 300 is not recommended).
    Highest speed: 4,500 RPM.
  • Soft start is programmable and will be set as soft as possible when you receive this motor. This program is very effective in reducing drive belt wear etc.
  • Braking strength is also programmable and will be set as low as possible. Personally I wish I could set it lower.
  • Self diagnostics with fault code chart and programming instructions are available on our web site.
  • Power out safety circuit. When the power goes out, speed must be returned to stop before the motor will restart.
  • Use at your own risk. Our liability is limited to the purchase price of this item.
